Defectors from Near North Korea’s Nuclear Test Site Show Evidence of Chromosome Mutations Due to Likely Radiation Exposure
It is going to be interesting to see if over time defectors from this area come down with a higher rate of cancer like what happened to people exposed to radiation at the Hiroshima and Nagasaki atomic bombing sites:

A quarter of North Korean defectors from regions near the northeastern Punggye-ri nuclear test site have shown chromosome mutations possibly attributable to exposure to radioactivity, data showed Monday.
Radioactive exposure tests conducted in 2024 by the Korea Institute of Radiological & Medical Sciences (KIRAMS) on 35 North Korean defectors from eight regions near the Punggye-ri nuclear test site found that 12 of them, or 34 percent, showed chromosome mutations possibly linked to radiation exposure, according to the unification ministry.
The regions include Kilju, Kimchaek and Paekam. Since 2006, the North has conducted all of its six nuclear tests at the Punggye-ri nuclear test site, located in Kilju County.
